When your furnace is working properly, it should provide warm air without generating too much noise. While it’s expected to catch your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional help.

Here are some of the most common furnace noises and what they might mean. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Tucker, Georgia.

1. Furnace Makes Banging or Knocking Sounds

You might have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s important to set routine furnace maintenance with ACS Heating and Air Conditioning. One of the things our technicians do during this service is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily vented outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, ACS Heating and Air Conditioning urges you to turn it off and reaching us at 770-450-1539. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous troubles that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air across your house. If the ductwork wasn’t installed right or is getting old, it can be noisy when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Call ACS Heating and Air Conditioning at 770-450-1539 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or chilly air across your house, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something small, like an unfastened screw, or something major, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 770-450-1539 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We realize that maintenance often slips your mind, but our professionals can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, ACS Heating and Air Conditioning can provide support. It’s critical to get loose ductwork taken care of quickly, as it can create comfort troubles in your residence and increase your heating costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off now and reach our pros at 770-450-1539 for help.

When you’re getting an uncommon noise from your furnace, ACS Heating and Air Conditioning is here to support you. Contact us at 770-450-1539 to book your furnace repair appointment right away.
